MIDI detuning

[Grieferus]

When switching to another song, EmuSC lowers sound by 1 semitone. But when switching to yet another song, EmuSC tries to return to normal tone after a couple of seconds while song plays and then it just goes out of tune.

A couple of questions to better understand the issue:

• Is this consistent every time you play the second MIDI-file that the pitch lowers by 1 semitone?
• Is this consistent across all MIDI files? (could it be that the MIDI file you are playing has SysEx messages that changes the tuning parameters?)
• Does the pitch parameters in Synth settings dialog appear to change from default values? (check both Master settings and Part settings: main)
• If you restart the synth (press space twice), is the pitch back to normal again?

1. Yes, it's consistent every time.
2. Apparently, only E1M1 detunes, due to pitch modification.
3. No, it remains the same.
4. Yes, it goes back to normal, unless I play second MIDI.

Quick update: any MIDI file that uses pitch modification detunes if played as third in the row. It's also important to point out that I hopped from one to another after couple of seconds.

Ok, thanks for the report. Will look into it when time permits, probably while working on the new interpolation solution.
